IMPROVEMENT IN WINDOW-SASH SUPPORTERS.

Specilieation forming part of Letters Patent No. 55,659, dated June 19, 1866.

To all whoml it may concer/a Be it known that I, H. O. HUNT, of Amboy, in the county oi' Lee and State of Illinois, have invented a new and useful Improvement in SaslrLocks orVi ndow-Fasteners; and I declare that the Jfollowing description is full, clear, and exact, reference being had to the annexed drawings, which make a part ot' this specification.

Figure l is a perspective view. Fig. 2 is an internal view, showing the relative position ot' the dilierent parts; and Fig. 3 is a representation of the case A, anchor O, and friction-roller E separated.

Similar letters of reference indicate correspondin g parts in the several igures.

'lhis invention relates to that class of sashfasteners which lock the window either up or down and at any desirable point; and it consists in a case, A, with its double inclines I) l1, with a corresponding slot, e, an a-nchor, O, with its double inclines ff", and africtio1'i-roller,E.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents acase of any suitable material, of such shape as to allow of a screw-hole in each end and the inclines b b between them. The central portion, containing the Aslot e, is raised enough to allow the anchor l and friction-roller E to slide freely between it and the sash to which it is fastei'led. The little knob or finger-piece r has a shank which passes through the slot c and is riveted to the anchor C, by which means the anchor is retained in the case and yet allowed to slide freely.

O represents an anchor, which is attached to the case A in the manner represented above,

and has double inclines ff situated just the reverse of the inclines b b, which form a recess for the roller E. rIhe anchor, following the window down byits own weight, is always in contact with the stop and locks the window down. When the window is to be raised, the anchor must rst be raised (with the linger under the knob) to the center of the case A, or till the knob r is at the center of the slot e, and held there till the window is at the desired point. when the window, being let go of, locks itself' instantly, the anchor being held till the weight ot1 the window rests upon it.

E represents a friction-roller, which is conned between the sash H, anchor O, and case "A, and, being allowed free play, prevents abrai sion between the case and anchor.

The whole being fitlyjoined together, is secured to the sash H by means of two woodscrews, and constitutes a neat, cheap, durable, and efficient lock, with but few parts and no spring about it to get out ot order.

Having thus described my invention, what I claim as new, and wish to secure by Letters Patent, is

l. The case A, with its double inclines b b and its correspomling slot c, all operating as and for the purpose shown.

2. The anchor C, with its double inclinesf f, and its knob or finger-piece r, operating as and for the purpose shown.

3. rIlhe frictiolrroller E, operating as and for the purpose shown.
